Collection Management and the realism within the school

Can it work?
The principles of the collection management policy (CMP) are clear and concise, laying out a direct path for selection and acquisition within a school. As the TL, to allow for the policy to proceed without hiccups, the Library committee must ensure that they help to promote the policy within the school and felow staff. The CMP will allow the TL to keep a track of resources being added to the resource collection(RC), and help prevent purchasing of resources that may be unneccessary.
It is often difficult to monitor specialist teacher purchases within a large school, as they feel that they are the leader within theri own field . As they do hold the knowledge and expertise within their field, similarly to the TL, they often feel that the acquisitions that they are making are relevant to the selection of resources within their specialist field. This may be the case, for most items. The TL can ask such questions as; Will this resource be used? Will it fit the curriculum in 3 years time? Do we have a resource that is similar? Is there an electronic version the same or similar?
These questions will need to be asked tactfully and sincerely as the resources being added will be part of the RC, thus part of the accessioning and stocktaking procedure conducted by library staff.
Much to consider.
