The catalogue of reconstruction maps of Bohemian character is designed as a part of a project called 'The Atlas of Czech History' which is being worked on by the Historical Institute within the current research intention 'Czech Historical Space within the European Context. Diversity, Continuity, Integration'. In September 2006 it was suggested to prepare and publish this catalogue, either with an atlas or as an independent volume. The catalogue of reconstruction maps will not include all reconstruction maps from the atlases and will have annotations. The main criterion for including individual maps into the catalogue is their professional value (maps with obsolete contents and those surpassed by later research, derived maps, the ones taken over from other works or re-printed, often simplified, maps published just for information shall not be included in the catalogue). The excerption focused on the period after 1945, however, older maps, if still valuable, shall be registered as well. Map contents will be specified by explanatory comments. The catalogue (index) structure - which needs to be clear and user-friendly - will result from continuous confrontation between the primary rough concept, derived from the general concept of Czech history, and specific materials obtained from excerpts. From the technical point of view, there are two basic approaches available - a text and a database; the possibility of fulltext searching places a text file to the same level as a database from user's point of view, whereas the profit resulting from the possibility to ask more complicated 'multiple-level' questions (as we know them from library and bibliographical databases with dozens or hundreds of thousands of items) seems to be hardly apparent in the given situation. It is assumed that beside a printed issue (with a list of authors, geographical locations and possibly also subject matters), the text - or possibly the database if this form is selected - of the catalogue will also be published in the electronic version, either on the Internet or as a CD-ROM.
