As these manuscript lists came to be copied and re-copied, it was seen that their usefulness would be increased by putting the words and phrases into alphabetical order, whereby a particular word could be more readily found than by looking for it in a promiscuous list of some hundreds or thousands of words. The first step was to bring together all the words having the same first letter. The copyist instead of transcribing the glossary right on as it stood, extracted first all the words beginning with A; then he went through it again picking out all the words beginning with B; then a third time for those with C, and so on with D, E, and the rest, till he had transcribed the whole, and his copy was no longer in the fortuitous disorder of the original, but in what we call _first-letter_ order. A still later scribe making a copy of this vocabulary, or possibly combining two or three lists already in first-letter order, carried the alphabetical arrangement one stage further; instead of transcribing the A-words as they stood, he went through them, picking out first those that began with Aa-, then those in Ab-, then those in Ac-, and so on, to Az. Then he did the same with the B-words, picking out first all in Ba-, then Be-, Bi-, Bl-, Bo-, Br-, Bu-, By-; and so exhausting the B-words. Thus, at length, in this second recension, the Vocabulary stood, not yet completely alphabetical, but alphabetized as far as the second letter of each word. All these stages can actually be seen in four of the most ancient glossaries of English origin that have come down to us, known respectively, from the libraries to which they now belong, as the Leiden, the Epinal, the Erfurt, and the Corpus (the last at Corpus Christi College, Cambridge). The Leiden Glossary represents the earliest stage of such a work, being really, in the main, a collection of smaller glossaries, or rather sets of glosses, each set entered under the name of the treatise from which it was extracted, the words in each being left in the order in which they happened to come in the treatise or work, without any further arrangement, alphabetical or other. It appears also to incorporate in a final section some small earlier vocabularies or lists of names of animals and other classes of things. In order to discover whether any particular word occurs in this glossary, the whole work from beginning to end must be looked through. The first advance upon this is seen in the Epinal Glossary, which uses part at least of the materials of the Leiden, incorporating with them many others. This glossary has advanced to _first-letter_ order: all the A-words come together, followed by all the B-words, and so on to Z, but there is no further arrangement under the individual letters[1]. There are nearly fourteen columns of words beginning with A, containing each about forty entries; the whole of these 550 entries must be looked through to see if a given word occurs in this glossary.
