The Catalogue of printed books consists of three main sequences:
The Online Catalogue lists material catalogued from 1990 onwards (including many books published before this date.) Following a catalogue conversion project, most of the books in the Irish Collection listed in the two older sequences now appear in the OPAC, along with those in the LO, Joly, Thom and Dix collections.
The Guard Books
This sequence consists of 446 large bound volumes. It is arranged in alphabetical order according to author. Anonymous works are entered under title. This sequence contains material acquired and catalogued up to 1969.
This lists material catalogued from 1969 to 1989, regardless of date of publication. In other words, many pre-1969 books are listed in this sequence.
Many books held by the Library are very rare, or in some instances unique. Access to digital databases lessens the wear and tear on these often fragile items, and also allows for greater search capabilities. Many older texts – many of which are in the library collections, others not - may now be consulted in digital form. Pre-1701 printings may be consulted on EEBO, and many eighteenth-century texts are available on ECCO. These may be consulted in the Online Services Room.
