Library Study Space Campaign

There are over 3,100 study spaces across the Library's physical estate. These study spaces are generally available on a 'first come, first served' basis. At times of peak demand (particularly in the run up to exams), study spaces can come under intense pressure. To address this issue, and to ensure that all readers have a reasonable opportunity to find a suitable study space, the Library implements the following seating policy:

Readers are not permitted to reserve study spaces by leaving their belongings or books on seats and desks. Library staff may remove belongings or books left unattended for more than 60 minutes at any study space, except for officially reserved carrels.

Nonetheless, the practice of 'desk-hogging' (i.e., the practice of leaving books and personal belongings unattended for long periods of time – sometimes overnight – thus preventing others from using those desks) is a perennial problem that can be a significant source of frustration for other readers. The Library is addressing this problem directly by launching a Library Study Space Campaign. Starting on Tuesday 19 March 2024, a dedicated steward team will patrol Library reading rooms to free up study spaces that have been unoccupied for more than 60 minutes. The team will operate using the following procedure:

  • Leaflets will be left at study spaces observed to be unattended. The leaflets will indicate the time at which the study space was observed to be unoccupied and the time at which it will be cleared should the reader fail to return within the allotted 60-minute period
  • Any books and belongings left at the study space will be cleared to a box and moved to a designated storage area on the same floor. This includes laptops and other portable devices, so readers are strongly advised to back-up all work regularly 
  • The information on each leaflet will also be recorded on separate clipboard sheets to ensure transparency

The Library Study Space Campaign relies on the cooperation of all readers. We ask that you support the study space team to ensure a level playing field for those who come to the Library to study and prepare for exams. You can assist us by not leaving laptops, phones, USB drives or any other valuables unattended for any length of time and by sticking to the 60-minute rule.

The Library shall not be held responsible for damaged or stolen belongings.

Library Declaration

All readers are required to observe the terms of the Library Declaration.

The following is a translation of the declaration:

"I,...., do solemnly promise that, whenever I enter the Library, I will treat the books and other furniture of the Library in such fashion that they may last as long as possible. I further promise that neither will I myself take away any book nor designedly damage or write in or badly treat in any way whatever any book, nor so far as in me lies will I suffer such things to be done by others. All and each of which things and all the Statutes of the Library, in as far as they concern me, I promise and vow faithfully to observe."

In its original Latin:

"Ego,...., solemniter promitto, me, quoties in Bibliothecam hujus Collegii venire contigerit, libros ceteramque Bibliothecae supellectilem sic tractaturum, ut superesse quam diutissime possint. Promitto etiam quod neque ipse librum aliquem asportabo, sponte corrumpam, interscribam, aut alio quovis modo abutar, nec ab aliis haec fieri (quantum in me est) permittam. Quae omnia et singula, et omnia Bibliothecae statuta (quantum ad me attinet), me fideliter observaturum promitto, et spondeo."

Sanctions for Breach of Library Regulations

Breach of the Library regulations will result in sanction by the Librarian, the Junior Dean or the Disciplinary Committee, as appropriate.

Appeal against a Library penalty or decision of the Junior Dean is to the Disciplinary Committee.

The Librarian operates a system of penalties (as approved from time to time by the Board) for breaches of the Library regulations.

Penalties may include fines, administrative and other charges, ejection and temporary or permanent exclusion from the Library and/or the College and/or the University, and the confiscation of any personal property brought into or used within the Library in breach of Library and/or any other applicable College regulations.

The Library shall not be responsible, in any way whatsoever, for any property so confiscated.

Senior Sophisters and other final year students who have passed their final examinations are required to return all books to the Library within one month following their examinations.

The Library will return records of books and fines outstanding to the Proctors' Office, for the purpose of alerting students to their obligation to clear their Library records so that they may proceed to Commencements.
