Why an organisation might use blogging software like Blogger or Wordpress to create a website.

Content Management System such as Blogger or Wordpress provide for most customer needs where a unique CMS is unnecessary. Customers don't need to know any programming code to begin, instead templates, layouts and widgets can be added by drop and drop mechanisms and simple menus, lowering the learning curve for any customer's management of their site while being feature rich, intuitive, and customizable. Both web hosting services employ multiple server server setups, strategically place around the world so that no matter where you are, the created website will load quickly. These services are reliable as well system maintenance is carried out by experts so the customer doesn't need to worry about computer software problems. As these services are provided by without cost, there is already a significant return on investment before any custom templating or other advanced development services are required.

The downside to building a library website this way is the limited set of applications the website can carry out. Libraries websites need features such as:
Sophisticated search tools to search their catalogue.
Large databases to store their catalogue.
Modules for online membership accounts including the ability to renew items, pay fines, place reservations.
Modules for interlibrary loans, the ability to access and communicate with national databases.
Modules for audiobook or other electronic downloads.
Integrated library management system application program interface.
Digital object management system application program interface.
The ability to interface with catalogue systems to keep up to date.
Most of these concern back of house systems that the library user does not need to be aware of in the display of library website but if a library cannot deliver proper services it is a failure.
