This series consists of the daily diaries Oppé used to document aspects of his day to day life. His tone is typically candid: he regularly references his mood and writes unguardedly about everyday events & the people in his life. Entries are usually composed of brief sentences, with abbreviations & shorthand regularly employed. The only real exception to this are the earliest volumes, 1893-1918, which tend toward longer, slightly less prosaic entries.
A typical entry usually includes Oppé's comments on the following:
-quality of sleep and general mood
-everyday work & life events
-interactions with family
-lunching and dining with friends and aquaintances (including accounts of their conversation or his observations of them)
-time spent at various gentleman's clubs (including accounts of his interactions and observations of friends and aquaintances)
-visits to galleries and collections to look at drawings or conduct research
-visits to art dealers to purchase or study drawings
-his academic work or letter writing
Many of the diaries include more detailed information about financial transactions and accounts - including, on occasion, payment for works of art - in the back pages.
The daily diaries run from c 1893-1955, but there are some gaps in the sequence: the volumes are sporadic between 1893-1922 and there is a gap between 1952-1954. It is not clear whether Oppé compiled daily diaries that cover these years.
Each diary has a separate catalogue entry, but details given are brief: in most cases only listing the overall date range of the volume. The entries are too dense to reference specific information, but it should be noted that Oppé frequently discusses his research and publications, other art historians, exhibitions and institutions, and his purchases and opinions of works of art.
Most diaries are untitled, so a number was assigned during the process of cataloguing. A few diaries were titled by Oppé, and this information has been included in the title of the relevant catalogue record, after the assigned number.
