Cambridge University Library Classification Scheme

"This is the Library's 'three-figure' classification scheme which is used to determine the subject stem of the classmarks of the great majority of monographs on the open shelves. (It is also used in a simplified form in combination with various prefixes for special types of material: R, the reference collection in the Reading Room; S, 'select' books on closed access; P, L, T, Q, primary, secondary, select and dead periodicals, respectively; Z, mutilated books.

Pendlebury Library of Music Classification System

"Understanding the basic principles of the classification system will make browsing and finding materials in the Pendlebury Library a lot easier. Every item in the library has a specific and unique shelf number. It is this number that is crucial for locating the item on the shelves. There actually are three different classification systems; one for bound volumes (books and scores), one for unbound music and one for other media (CDs, Videos, DVDs, Microfilms etc.)."

Fission Yeast Phenotype Ontology

" The Fission Yeast Phenotype Ontology (FYPO) is a formal ontology of phenotypes observed in fission yeast. FYPO is being developed to support the comprehensive and detailed representation of phenotypes in PomBase, the online fission yeast resource. Its scope is similar to that of the Ascomycete Phenotype Ontology (APO), but FYPO includes more detailed pre-composed terms as well as computable definitions."

Structural Classification of Proteins

"SCOP contains the domains of all PDB entries available at the time of the current release's construction. For each of these entries a coordinate file is available and can be displayed via the various graphical interfaces. The sequence of each protein chain has also been extracted. The release also contains many literature references. These are structures that have been published in sufficient detail to be classified in SCOP, but where the coordinates are not yet available from PDB.
