We have been dealing with primary sources a lot in the past, but now we are starting to see some analysis of data from primary sources as well as some other presentations of primary source information in indirect form. For example, Polarlab's Clan Census is not a primary source but rather is studying what is known about older clans and how many members they had. Because of this, we need to start accounting for secondary and tertiary sources. Polar's census counts as a secondary source.
But what about the LBP Union Census? It can sometimes be difficult to distinguish primary, secondary and tertiary sources from one another. I would say that the Union Census is a primary source because the data it obtained was from the reports of clan governments, while Polar's census has a more specific criteria for member counting. Polar mainly looks for association with clans through avatars and uploaded photos when making his counts. By doing so he is using a multitude of primary sources like those photos and profile pictures to determine whether or a not a member was involved with a particular clan.
What about Polar's autobiography and my journals? These are observations of history. According to the American University Library, journals and autobiographies are primary sources. Biographies (not Polar's deceptively titled autobiography) are secondary sources.
What are secondary sources? Secondary sources are, again according to the American University Libary, are "interpretations and analyses based on primary sources." Think of scholarly journals, biographies (as I mentioned), magazines.
Tertiary sources are the odd cousin of secondary sources and include things like bibliographies, textbooks, etc. This one is a bit more difficult to distinguish. Generally this can be thought of as the categoory that indexes primary and secondary sources. Another example is something like an almanac or excyclopedias. According to the James Cook University, tertiary sources can be "works which index, organize and compile citations to, and show you how to use, secondary (and sometimes primary) sources." (Such as this wiki?)
To the point, I will be creating categories for these two different sources to enhance our understanding of clan history.
