Their characteristics, derived for the choice and form of the authors persons and bodies and of the titles from the recommendations of the Principles of Paris and for descriptive cataloguing from the directives of the various ISBDs, have promoted their diffusion in different types of libraries throughout the country. We can therefore consider the RICA as a national code in all respects.

The RICA were not however conceived as a definitive and unchangeable structure. It had already been indicated in that a permanent Commission was required to care for their constant update and any possible simplifications. The tasks and composition of this Commission were established at the end of with a view to updating and revising the rules according to international developments and directives, so bringing them into line with the evolutions that had taken place in the span of over twenty years since their publication.

In the last year the Commission has considered it opportune to devote part of its activities to an in-depth examination of the prospects offered by the new model derived from the IFLA's study on the functional requirements for bibliographic records FRBR. The aim of the study is the creation of a structural scheme in which every bibliographic entity, duly defined and 7with all its characteristics, is logically correlated to other similar or different entities in an articulated grid.

This should then satisfy the various demands that different types of users make in their search and consultation of bibliographic records. The work that the Commission has carried out up to this time has consisted in an as careful and documented as possible control of the various ways of application of the structural design of the model, with all its innovative implications, on the framework of a code of cataloguing rules. It has also studied the actual effectiveness and practical qualities of the solutions derived, from the point of view both of the results and of any possible obligations.

As well as examining the application of the FRBR model in its complete form, the possibility of its development in a reduced and personalized form was also considered. This would be done according to the requirements of the individual institutions and the data could be increased and enriched during the reutilization of the bibliographic record in a cooperative system.

This solution could satisfy various requirements, including that of the limitation of cataloguing costs.

The RICA are fundamentally dedicated to the choice and form of the headings for authors and titles. The new structure planned for a cataloguing code will still be focussed mainly on the access points, including all the types of responsibility connected with new materials and formats. As regards the bibliographic description, the code will continue to provide directives at a general level, referring to the individual ISBD for more detailed indications.

This contribution should be considered as an on-going document which contains part of the work carried out by the Commission and the conclusions reached thus far.

Milano: Editrice Bibliografica, Bollettino AIB, vol. This book appears useful and well written, in particular for who is new to the cataloguing of remote electronic resources. In the general organization of the volume, the lacking of an analytical index - which would have simplified very much the reference - is a burden. In this type of work, there is no glossary brief and schematic, with the most useful definitions too.

L'opera recensita si presenta nel complesso come utile e ben fatta, in particolare per chi si avvicina per le prime volte alla catalogazione di RER. Pesa, nell'organizzazione generale del volume, l'assenza di un indice analitico, che avrebbe semplificato non poco la consultazione. Maria Cristina Bassi.

Information technology and library technology. Andrea Marchitelli.Half a century has passed since the hydrogen-bonded secondary structures of polypeptides and proteins were first recognized. This review examines the nature of intramolecularly hydrogen-bonded conformations of hybrid peptides formed by amino acid residues, with a varying number of backbone atoms.

Bollettino AIB.

The available crystallographic information on hydrogen-bonded hybrid turns is surveyed in this review. Examples of both peptide helices and hairpins are presented. The construction of globular polypeptide structures using diverse hybrid sequences appears to be a realistic possibility. A little over 60 years ago, Maurice Huggins reviewed the hydrogen-bonded structures of polypeptide chains, at a time when no detailed structural information was available on oligopeptides and proteins Huggins Attempts to rationalize limited X-ray diffraction data in terms of regular hydrogen-bonded polypeptide structures were summarized by Bragg et al.

This expectation has been amply fulfilled in the last half century with the result that almost every feature of polypeptide chain folding is now firmly established by experimental studies. An interesting feature of the Bragg, Kendrew and Perutz paper is the consideration of intramolecularly hydrogen-bonded structures, which were later shown to be stereochemically and energetically unacceptable.

Pauling's remarkable insights led to the correct formulation of the hydrogen-bonded helical structures of polypeptides Pauling et al.

Current interest in the hydrogen-bonded structures of polypeptides chains stems from the realization that the repertoire of polypeptide chains can be vastly expanded when backbone-homologated amino acid residues are introduced Gellman ; Cheng et al. The stereochemistry of the polypeptide chain is best described by analysing the various orientations of two planar peptide units linked together by a central tetrahedral carbon atom.

The nature of polypeptide chain folding is determined by short-range non-bonded interactions and intramolecular hydrogen bond formation between acceptor CO and donor NH groups. Over the course of a little more than half a century, the principles governing the folding of polypeptide chains and the nature of the stable secondary structures have been well established. For unwary readers, a note of caution regarding nomenclature may be in order.

A convenient way out of this confusing situation does not appear to be feasible at this time, since usage of the various turns is well entrenched in the literature. Figure 1 shows the Ramachandran map for the l -alanine residue. The contact criterion, which simply states that non-bonded atoms cannot approach one another at distances less than the sum of their van der Waals' radii, has been found to be an excellent filter for distinguishing stereochemically allowed and disallowed conformations.

The use of backbone torsion angles as variable parameters permits the analysis of a three-dimensional problem in two-dimensional, torsion angle space.

The use of dihedral angles as descriptors of local conformations at individual residues has permitted systematic analysis of backbone structural features in a large body of experimentally determined protein structures.

The characterization of the helix [ M 2. This approach is illustrated below with specific examples. The C 7 structure is effectively determined by the conformational preferences at a single residue.

They have been classified into distinct groups defined by the torsion angles at the two central residues. Specific families in both C 10 - and C 13 -turn types can be successively repeated generating regular polypeptide helices.Associazione italiana biblioteche", che ha mantenuto fino al I legami conducono ai testi integrali eventualmente disponibili.

L'opera di Ranganathan ha avuto un notevole impatto soprattutto nell'ambito della teoria della classificazione. Tra il e il sono state pubblicate dall'editrice Le Lettere le traduzioni di due opere fondamentali di S.

A seguito di queste due pubblicazioni, sono stati tenuti diversi seminari a Firenze, Roma, Padova, dal titolo Leggere Ranganathanproprio allo scopo di promuovere la lettura diretta di Ranganathan in Italia. Questa pagina si propone di offrire alcune notizie essenziali su questa eminente figura della biblioteconomia mondiale, a partire da un breve profilo biografico e da una bibliografia delle pubblicazioni su S. Ranganathan in lingua italiana, che aspira a diventare, nel corso del tempo, esaustiva.

Ranganathan segue con estrema riluttanza il consiglio di un suo collega, che lo invitava a partecipare al concorso per un posto di bibliotecario nella Madras University; lui stesso racconta:. La mia esperienza come utente della biblioteca aveva fatto sorgere in me pregiudizi nei confronti del lavoro in biblioteca.

Ma la sua insistenza mi fece firmare la richiesta, ma con grande riluttanza. Il 4 gennaio dovetti passare dal college alla biblioteca e lo feci a malincuore. Gopinath, un suo allievo, riferisce che. Ranganathan ci raccontava spesso che non aveva mai aspirato a diventare un bibliotecario. Diceva che era stata la Provvidenza. Nessun essere umano, a parte il personale.

Che differenza dalla vita al college! Il presidente cerca di rassicurarlo, ma Ranganathan si tranquillizza soltanto quando gli viene promesso che se si fosse sentito ancora a disagio al suo ritorno dal viaggio in Inghilterra, sarebbe stato reintegrato alle sue mansioni di insegnante. Il 30 settembre sbarcai a Londra. Lo scopo era studiare biblioteconomia e osservare i servizi bibliotecari. Berwick Sayers. Ecco cosa racconta del codice catalografico angloamericano:.

Il primo motivo di rifiuto era il metodo di insegnamento usato. Un quarto motivo nasceva dalla discrepanza tra le regole insegnate in classe e quelle prescritte come valevoli nelle lezioni pratiche […] Quinto, i dettagli bibliografici sul formato, la collazione e le note tipografiche erano troppo preponderanti nelle lezioni pratiche.

Per quanto riguarda le prassi biblioteconomiche, Ranganathan racconta:. Tutte queste informazioni e regole empiriche non potevano essere ridotte a una manciata di principi fondamentali? Non si potevano ottenere tutte le regole mediante la deduzione dai principi fondamentali? I principi fondamentali non contenevano, come implicazioni necessarie, molte altre regole non ancora attuali o note? Queste domande cominciarono a ronzarmi in testa … [10]. Il 21 luglio ripresi servizio presso la Madras University Library, dopo il viaggio di studio in Europa.

Pochi anni dopo avere riorganizzato la Madras University Library, Ranganathan promuove la fondazione della Madras Library Association, che avviene nel In questo periodo visita nuovamente per motivi di studio la Gran Bretagna nelquando viene costituito il Classification Research Group [13] e poi gli Stati Unitie inizia a collaborare con la FID Federazione Internazionale di Documentazione.
