The Bodleian Library is part of the Oxford University estate.
It is a fascinating site, bringing together a great number of resources. The one draw back is that not all the catalogue material cannot be freely accessed, but in my experience. You can use the Ask a Librarian feature and the staff will do what they can to assist. Alternatively you maybe able to access the resources either via a public library or University library.
A quick search of the catalogue for the name Butcher revealed some rather interesting features for a company in Birmingham, England as part of the John Johnson Pictorial Archive and like yesterday, this is something that I had not come across previously.
We do not touch upon all these resources within the duration of the Introduction to One-Name Studies course, but what I do hope, is that students are inspired to locate unusual resources and to see if there are references to their particular surname and then to follow the research path, documenting all the details and citations, along with the date accessed.
