# Judge the feasibility of hobbies through library borrowing history In theory, analyzing a person's library borrowing history can indeed infer his interests to a certain extent, but there are several aspects of this method that need to be considered.： ## Feasibility analysis -**Borrowing pattern recognition**: Frequent borrowing of books on specific topics may indicate continued interest in the field -**Borrowing depth**: Whether to borrow a series of books from entry to advanced may reflect the depth of learning -**Time trend**: Whether interest changes or remains stable over time ## Limiting factor -**Privacy issues**: In most regions, library borrowing records are protected by privacy -**Incomplete information**: It does not reflect online reading, book purchase, or other ways of acquiring knowledge -**Borrowing≠ interest**: It may be for study or work needs rather than personal interests -**Passive borrowing**: May borrow on behalf of others or subject to course requirements This kind of analysis does exist in the field of data science, but it must be carried out with respect for privacy and proper authorization.
