What is the Repertorium?
The Repertorium is an annotated listing of publicly available sources via the Internet that may be used by serious researchers for investigative work. The Repertorium is annotated, arranged by keyword, updated frequently and irregularly, and open. The Repertorium is used worldwide by thousands of customers on a daily basis, mainly government institutes, law enforcement, military, international relations, financial and business analysts etc.
How to use
One golden rule in the Finer Art of Searching is think in sources. The first thing you do when handling a reference question is to ask yourself "what source may likely have the answer to this enquiry?".
The Repertorium can assist here to guide you quickly to the most authoritative sources.
The Repertorium comes in very handy if you are used to using Collection Plans. A collection plan is the management scheme and 'search plan' that will help the searcher in systematizing a research efficiently. All the sources in a collection plan are listed in the Repertorium. So, when searching for country information one does not jump directly to the category or block entitled 'country information', but one first writes down a plan of sources to use to compile country information.
In a country information plan, there could be categories such as: government information, maps, newspapers, harbour data, airport data, etc. Those categories are all listed in the repertorium and that is exactly how useful the Repertorium can be: in executing a precompiled Collection Plan.
The Repertorium has grown out of a need to keep track of interesting sources usefull for serious research. In the early nineties when I joined the Internet community I kept track of sources on paper. Then, I wrote my first HTML source book page to make it more efficient, using some HTML editor. Many years later I found that simply using XML with XSLt is the most efficient way of keeping track of developments, also staying completely independent from platforms and software.
The first Repertorium was written in HTML and called Reuser's Repertorium. One single HTML file with hundreds of links became off course unmanageable, so for the second main release, the XML format was choosen, also to allow other editors to participate in the project. Hence the name: Reuser's new Repertorium.
The word Repertorium is derived from the Latin and is used by librarians to refer to little reference books for purpose of looking up things.
Arrangement of sources
The Repertorium consists of three main columns. Column number one is the table of contents. Column number two is the first array of sources. Column number three is the second array of sources.
The table of contents (TOC) consist of four blocks.
The sources are described in terms of URL, title, and a very small annotation. Sources are systematically grouped in blocks devoted to a particular main subject (such as: newspapers, country information). Each block is devided in subheaders, typically by kind of background (top choices, international, local, meta sites, etc.).
Blocks may start with a little explanation as to the content of the block. Also, subheaders sometimes have descriptions for clarifications.
Each block ends with a very small 'menu' to jump back to the TOC category Searchers, Premium, Reference, or, Subject.
There are two versions of the Repertorium. The Full Version includes explanations and annotations, the Short Version is just the links.
The Repertorium is updated regularly and infrequently. There is a little Help button where I try to keep track of major changes.
