What is the status of the Montessori Bibliography Online?

I periodically like to take stock of the content included within the bibliography in order to do a general audit of the data and also to get a snapshot of the entire dataset. Generally, I focus on 5 areas:

  • Type of entry
  • Language of content
  • Year of publication
  • Available or unavailable in digital form
  • Tagged or untagged

For the most part the scope of these categories are self-evident, however there are some nuances to consider. Type of entry refers to the type of material – journal article, book, book section, et cetera – in which the citation references. Language of content refers to the language(s) which the referenced document is written. In some cases a document may be written in one or more languages. Year of publication is pretty self-evident, this refers to the year in which the document was published. In some cases the date of publication is unknown or unidentified so this field is left empty. Available or unavailable in digital form refers to whether the document is accessible digitally from a reputable and reliable source. This includes content that is freely available as well as content available behind a paywall. Finally, tagged or untagged refers to whether I have completed a basic level of cataloging of the content. As I add content to the database I attempt to assign relevant tags – this has been a challenge to maintain.
