What are the implications for the role of TL?

Just cataloguing a couple of new Geography text books and noticed that they have built-in information skills.

Geography for Global Citizens

3rd ed. p. 40 has a section on using mind maps, p. 48 a section on using the internet.

Geography for Australian Citizens

3rd ed. includes information about how to design a webpage (p. 177) and criteria for evaluatiing a webpage (p. 278).

Is this an impact/the result of lack of TLs in schools already?
Will teachers be confirmed in their perception that a TL is not necessary if they are doing this themselves anyway?
